Stat. 267. 5°54'S., i32°s6'.7E. 9S4 m. A dead fragment. 

 Stat. 297. io°39'S., i23°4o' E. 520 m. A small branch. 



In the Indian Museum there is a large piece of this species from the N. Atlantic 

 (" Cfrudan" Expedition) some of the smaller branches of which agree in every respect with the 

 Siboga fragment from Station 297. As to the identity of the small dead fragment from Station 

 267, I am not quite certain. 



Distribution. N. Atlantic, Mediterranean, deep basins of East Indian Archipelago. 



51. Amphihelia ramen Muller, Duncan. 



Amphihelia rautca Martin Duncan. Trans. Zool. Soc. Lond. VIII, 1874, p. 326, pi. XLIV. 

 figs. 1 — 3, pi. XLV. figs. 4 — 6, pi. XL VI. figs. 1 — 19. 



Stat. 95. 5°43'.5N., ii9°4o' E. 522 m. Two dead fragments. 

 Stat. 156. o°29'.2 S., 130 5'-3 E. 469 m. Some dead fragments. 

 Stat. 251. 5°28'.4S., 132 o'.2 E. 204 m. Some fine branches. 



According to Martin Duncan all Diplohelice with costal strise are referable to this 

 species, which thus includes Amphihelia mioecsnica Seguenza, Amphihelia atlantica and ornata 

 Duncan, Diplohelia meneghiniana and doder leinia and sismondiana Seguenza, and Diplohelia 

 ftrofunda Pourtalès. The last named, however, is a Coenopsammia. 



The fine specimens which I identify with this variable species exhibit very close and 

 regular budding and but slight tendency to anastomosis. 



Distribution. Both sides of N. Atlantic, East Indian Archipelago; Sicilian Tertiaries.

Stat. 12. 7 15' S., 11 5 15'. 6 E. 289 m. Two small fragments. 

 Stat. 95. 5°43'.5X., U9°4o' E. 522 m. Numerous branches. 

 Stat. 156. o°29'.2 S., 130 S'.3 E. 469 m. A small fragment. 



This species cliffers from A. oculata chiefly in the greater density of the coenenchyma 

 and the polish of its surface, and in the greater depth of the calicles. In some of the calicles 

 there are small paliform lobes on the septa of the second cycle. 



Distribution. East Indian Archipelago.
